application filed July 29,

Be it known that'l, Ronnn'r L. DUKE, a

citizen of the United States, and a resident 1 of Columbus, in the county of Muscogee and and useful Improvements in Spinning or" .'*W1nding Machines, and do hereby de- St'ate of Georgia, have invented certain new f'clare the following to be a full, clear, and

I exact. description of-the invention, such as will enable others "skilledjin the art to which it appertains tomake and use the same. 7

This'invention relates to an improvement in spinningp winding machines in which means. are -employed for traversing the thread guides to build *up .the bobbin,my improvements having piartieular reference to "bunclibuilding attachments for spinning machines such as employ ring rails and opersting means therefor to effect traverse of the thread. ()ne object of my invention is to provide a buncherattachment for bobbins usedin automatic looms, which shall besun is in construction; which shall be controlled by the operation of the builder mechanism, and which will result in causing a reduction of waste by allowing a maxi= mum amount of yarn to be removed from the bobbin, and prevent thin places in the woven 3 illustrating details,

I cloth by insuring uniformity in the size of bunches which actuate the feelers so that a minimum amount'of waste will be left to be cut off the'bobbins, thus saving both in material aiidlabor.

With this and other objects in view, the

"invention consists in certain novel features of construction and combinations of parts ashereinafterset fo rth and pointed out n the claims.

In the accompanying drawings. Figure .l is a view illustrating an embodiment. of my invention, and Figures 2 to 7 are views In the draw1ngs,l have illustrated the frame 1 of a spinning machine, on whichspindles 2 are suitably mounted to receive bobbins 3. A ring rail such as usually-employed in spinning machines of the-type'to which I have illustrated the application of my improvement, is shown at 4 and with this rail, a; liftin rod 5 is connected. The lower end of the lifting rod is provided with a head 6 which issupported on'a roll or stud 7 carried'by an arm S-of a bell-crank I i lever 9. A foot piece 10 is secured to the free'endof thearm 8 of the bell-crank lever and an upwardly projecting arm 11 of this 1921. Serial no. 488,325.

' lever is provided with a segment 12. To -th1s segment, one end-ofa chain-13 is suitably connected and the operation of this chain to move the bell-crank lever and oper ate the lifting rod 5 to raise the ring rail,

is controlled by a builder mechanism illustrated as' 14-. The mechanism above described is of usual construction and need not be further described in detail herein, except in so far as parts of my improvements are co-opcrati've therewith.

A bracket 15 is secured to and depends from one of the rails of the frame 1 and is provided With-a vertical slot 16 in which a stud 17 is adjustably secured lever '18- is pivotally mounted on the stud 17 and is provided with a weight 19. The depending portion of the lever 18 is made with an elongated slot 20 for the passage of bolts 21 whereby a lock aim 22 is adjustably secured to said lever 18, and in A lock eifect constitutes an extension thereof The arm 'or lock lever extension 22 is provided near its lower end with a slot or recess 23 which (under certain conditions) receives v the free end of the foot piece 10 to lock the traverse mechanism at or near the lower end of the throw thereof and permit the formation of a bunch on the lower portion of each bobbin as indicated at 24. .The

lock lever arm is provided just above the be made to engage so that the latter will be held down during dotting.

The locking devices which control the operation of the mechanism for causing the formation of bunches as previously explained, is itself controlled from the builder 'mechanism. A cam- 27 is secured to rotate withthe take-up gear 28 on the builder shaft 29,-said cam being disposed between lugs 30-30 projecting laterally fromv a longitudinally movable bar 81, the latter-being made with 'an elongated slot 32 for the accommodation of the builder shaft 29. The bar 31 is provided with an extension 33 adjustably secured thereto as indicatedat 34: whereby i-L said bar as a whole may be lengthened or shortened and the throw of said her may be adjusted by adjustin; the cam 27 relatively to the gear 528. Art-its free end, the bar extension 33 is provided with a lug 35 and the lock lever arm 22 is provided with a screw or stud 36 on which bar extension 33 is supported.

\Vhen the lock lever arm 22 is in engagement with the foot piece of the traverse mechanism to lock the latter during the formation of the bunches. it will be held in such position by the operation of the weight 19.

After the bunches shall have been formed, the cam 27 will operate to move the bar 31 and its extension 33 rearwardly so as to cause the lug 35 on the latter to engage the lower portion of the locking, device 18-22 and move the latter so as to release the foot piece 10 and thus permit the normal operation of the machine to effect the winding of the service threads or yarn on the bobbins.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is:

1. In a spinning machine, the combination with traverse mechanism and builder mechanism cooperable therewith, of a locking device for the traverse mechanism during the formation of bunches. a longitudinally movable bar, and cam means operable by the builder mechanism to move said bar and withdraw the locking device from locked relation relatively to the traverse mechanism.

2. In aspinning machine, the combination with traversemechanism and builder mechanism cooperable therewith, of a locking device to hold the traverse mechanism during the formation of bunches, a cam adjustably connected with a moving part of the builder mechanism, and a longitudinally' movable bar operable by said cam and having a part to engage a part of the locking device and move the latter out of locked relation relatively to the traverse mechanism.

3 in a spinning machine, the combination with traverse mechanism and builder mechanisni cooperab-le therewith, of a locking device to hold the traverse mechanism during the formation of bunches, a longitudinally movablebar comprising two members, one adjustable longitudinally with respect to the other, and means operable by the builder mechanism for moving said bar longitudinally to release the locking device from the traverse mechanism.

4. In a spinning machine, the combination with a ring rail, 21 bell-crank lever, a lifting rod between an arm of said lever and the ring rail, builder mechanism cooperable with said'bell-crank lever. and a foot piece on said. bell-crank lever, of a weighted lock lever provided with an adjustable lock arm having a slot or recess to receive said foot piece, and means operable by the builder mechanism to move said lock arm out of engagement with said foot piece.

5. In a. spinning machine, the combination with a frame, traverse mechanism and a builder cooper-able with said traverse mechanism, of a bracket secured to the frame. a weighted lever-having vertically adjustable pivotal connection with said bracket, a lock arm adj ustably connected with said lever and having a slot or recess to receive a part on the traverse mechanism, a. lug on the lever above said slot, a lug on the lever below said slot. a longitudinally movable bar comprising relatively adjustable members, a. part on the'lock arm to support said bar, a part on said bar cooperable with the lockarm to disengage the latter from the traverse mechanism. and means operable by the traverse mechanism for moving said bar longitudina-lly.

In testimony whereof, I have signed this specification in the presence of two'subscribing witnesses.

ROBERT L. DUKE.
